Sony PCG-R505DLP Wifi
You are better off buying a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. A lot of newer wireless adapters are simply plug and play, in that you just plug it in the USB port and the operating system will take care of the rest. The WiFi in your laptop, if so equipped, uses an adapter in order to talk to your home network. Buying a USB wireless adapter is quick and painless because the only thing you have to know is what OS you are running on your Sony laptop.
Key clues to watch for in a failing onboard WiFi
- The WiFi adapter on your laptop does not connect at all
- The WiFi drops multiple times over and over again
- The wireless adapter driver gives errors when installing
